I've done it for 30 years, only had a problem once where a State trooper showed up. We were far off the road, but he had heard that the car I was pulling out had rolled (I found out then that it had but the new driver had not been in it and it had little damage). He was upset with me and really chewed me out, he described the problem with lack of proper lights and insurance in case we caused another accident. But he let me go. I still do it, but I check the vehicle out real close before connecting to it.
